WebArea of a circle is the region occupied by the circle in a two-dimensional plane. It can be determined easily using a formula, A = πr2, (Pi r-squared) where r is the radius of the circle. The unit of area is the square unit, such as m2, cm2, etc. Area of Circle = πr2 or πd2/4, square units. where π = 22/7 or 3.14. WebDec 19, 2015 · 1. In fact, once you have spotted that it is a right triangle there is a simple formula for the diameter of the inscribed circle. d = a + b − c. So your radius is: r = ( 8 + 15 − 17) / 2 = 3. It follows from two ways to compute the area of the triangle: A = a b / 2.
WebJul 3, 2024 · where d is the diameter of the circle, r is its radius, and π is pi. So if you measure the diameter of a circle to be 8.5 cm, you would have: C = πd C = 3.14 * (8.5 cm) C = 26.69 cm, which you should round up to 26.7 cm Or, if you want to know the circumference of a pot that has a radius of 4.5 inches, you would have: WebJan 16, 2024 · You can use the area to find the radius and the radius to find the area of a circle. The area of a circle is the space it occupies, measured in square units. Given the area, A, of a circle, its radius is the square root of the area divided by pi: r=\sqrt {\frac {A} {\pi }} r = πA. The formula for radius to area is: A=\pi {r}^ {2} A = πr2.
WebThe diameter of a circle is the distance from one side of a circle to the other through the centre. The radius is the distance from the edge of the circle to the centre. The diameter is... WebWell, the radius is equal to 1/2 the diameter. So this whole distance right here is 10 over pi meters. If we just 1/2 of that, if we just want the radius, we just multiply it times 1/2. So …
